Resumo: | This project description presents a research and development work whose primary goal was the design and implementation of an Internet Protocol (IP) network distributed video quality assessment tool. Even though the system was designed to monitor H.264 three-dimensional (3D) stereo video quality it is also applicable to di erent formats of 3D video (such as texture plus depth) and can use di erent video quality assessment models making it easily customizable and adaptable to varying conditions and transmission scenarios. The system uses packet level data collection done by a set of network probes located at convenient network points, that carry out packet monitoring, inspection and analysis to obtain information about 3D video packets passing through the probe's locations. The information gathered is sent to a central server for further processing including 3D video quality estimation based on packet level information. Firstly an overview of current 3D video standards, their evolution and features is presented, strongly focused on H.264/AVC and HEVC. Then follows a description of video quality assessment metrics, describing in more detail the quality estimator used in the work. Video transport methods over the Internet Protocol are also explained in detail as thorough knowledge of video packetization schemes is important to understand the information retrieval and parsing performed at the front stage of the system, the probes. After those introductory themes are addressed, a general system architecture is shown, explaining all its components and how they interact with each other. The development steps of each of the components are then thoroughly described. In addition to the main project, a 3D video streamer was created to be used in the implementation tests of the system. This streamer was purposely built for the present work as currently available free-domain streamers do not support 3D video streaming. The overall result is a system that can be deployed in any IP network and is exible enough to help in future video quality assessment research, since it can be used as a testing platform to validate any proposed new quality metrics, serve as a network monitoring tool for video transmission or help to understand the impact that some network characteristics may have on video quality. |
